Coin bank with combination lock



y 1963 P. NEMSKY com BANK WITH COMBINATION LOCK Filed Nov. 2'7, 1961 INVENTOR. PH. 1P A EMJIY United States This invention relates to a bank and, more particularly, to a bank that may be opened by operation of a combination lock.

The basic components of the bank of this invention include a coin receptacle, a base which functions as a closure, and combination lock means for releasably securing the receptacle to the base. In preferred form the coin receptacle is closed by a tray which extends over the open end of the receptacle. The receptacle and tray are jointly received between channel slideways on the base which permit them to be slidably positioned onto the base while being held against separation. A series of spaced lugs depend from the bottom of the tray and extend down through a slot along the length of the slideway when the tray is inserted therein. A series of blocking members are mounted below the slideway for reciprocal movement transverse thereof across the slot opening. Each blocking member is biased in one direction by a spring, and may selectively be moved in the other direction by operation of a cam, When the tray is fully engaged on the base the blocking members are disposed between the spaced lugs extending through the slot. Each blocking member has a notch or cut-out formed in the top side thereof which, when disposed directly below the slot permits the lugs on the bottom of the tray to pass freely as the tray is inserted and moved along the slideway. Some of the blocking members have the cut-out disposed so as to be aligned with the slot when the cam and blocking member are moved to one position and the other blocking members have their cut-out disposed so as to be aligned with the slot when in the other position. Thus, a proper combination of blocking member positions is required to permit insertion and removal of the tray and receptacle.

Objects and advantages of this invention will become apparent from the description following when read in conjunction with the accompanying drawings wherein:

FIG. 1 is an end view in section of a bank embodying features of this invention taken along line 11 of FIG. 2; and

FIG. 2 is a section view taken along line 22 of FIG. 1.

Referring now to the drawings in greater detail, the basic components of the bank of this invention include coin receptacle 2, a base member 4 and combination locking means 6. In the preferred form of the invention the coin receptacle actually comprises a plurality of compartments 8 of different sizes determined by the denomination of coin to be placed therein and each of the coin compartments has a slot 10 of appropriate size to permit insertion of that coin. Extending laterally from the open bottom 12 of the aligned compartments is a flange 14 which, in turn, is received Within a tray or closure 16 having an upwardly extending rim 18 around the periphery thereof.

The base member 4 may be supported on legs 20 and includes on the top thereof a slideway 22 having a flat slide surface 24 and opposing channel members 26 which receive both the rim of the closure and the flange on the coin receptacle, thus holding them against a separation. In the embodiment shown, the flange, tray and slideway are of rectangular configuration. However, it is to be understood that they may be in other shapes, including arcuate, so long as the flange and tray are received within the slideway and constrained to move parallel to the sides thereof. In FIG. 2 it can be seen that one end 22a of the slideway is open for insertion and removal of the flange 14 and closure 16. The other end 22b may be atent O 3,096,934 Patented July 9, 1963 closed or other suitable stop means provided to determine the fully engaged position of the flange and closure.

Depending from the bottom of the tray or closure is a series of spaced lugs 30 which are aligned in a row extending along the length of the tray and parallel to the side edges thereof. The lugs extend completely through a slot 32 in the bottom of the slideway 22 and pass therealong during insertion of the flange and closure. Immediately below the slideway is a series of blocking members 34 which are reciprocally mounted to be moved transversely across the slot opening 32 effectively to block passage of the depending lugs and, hence, to prevent removal of the closure and coin receptacle. However, each of the blocking members has a notch or cut-out 36 or 38 in the top surface thereof which, when aligned with the slot permits free passage of the depending lugs. As seen in -FIG. 1, the notches 36 in some of the blocking members 34 are spaced longitudinally from the notches 38 in the other blocking members. Each blocking member is urged outwardly by means of a compression spring 40 and functions as a cam follower with its rounded outer end 42 urged into engagement with the surface of a rotatable cam 44 mounted on a stub shaft 46 supported on the base 4. The cams may be turned from the position shown in solid lines in BIG. 1 to the position shown in phantom wherein a high portion 48 on the cam engages the rounded outer end 42 and urges the blocking member 34 to its innermost position. The cut-out portions 36 and 38 of the blocking members are associated with the two positions thereof so that the cut-outs in the inner position will be aligned with the slots when the cam lever is raised and those in the outer position will be aligned with the slot when its associated cam lever is depressed. Since some of the blocking members have their cut-outs in the inner position and some in the outer, it is apparent that only a predetermined combination of cam lever positions will position all of the blocking members so that the notches are in complete alignment with the slot to permit free passage of the lugs for insertion and removal of the receptacle flange and tray.
